Acceleration Enrichment Pulse Relay

SYSTEM FAILURE SYMPTOMS:
If the relay fails in the open position, the same hot start acceleration complaint noted in the previous test will occur.

TEST:

1. Plug in the acceleration enrichment pulse relay (D).

2. Remove the time and cold/hot start ground relays (CB-G)

3. Connect a jumper lead from pin 87 of the time relay (C-B) socket to ground.

4. Remove connector from the vacuum impulse switch. Connect a jumper lead from +12V to the brown wire in connector.

5. Connect a test light from +12V to pin 87 of the cold/hot start (G) relay socket.

6. The test light should begin to pulse rapidly on and off.

7. If inoperative check with the jumper leads in steps 3 and 4 removed.

At the pulse relay socket -



Terminal 15 +12V when rapidly accelerating the engine
Terminal 31 continuity with pin 87 of the time relay
Terminal 31b continuity with pin 87 on the cold/hot start relay.
